On Dec, 4 2009 USPTO made change to their patent site. This change prevented Accel ViewTIFF from detecting the last page of a patent. Printing or saving 'all' pages of a patent resulted in a never ending loop that would only be stopped by the user cancelling the operation.

The new version (4.6.0.4) at our web site fixes this problem and is free to users who purchased their license within the last 6 months. If you purchased before this date, your will need to purchase an upgrade. Downloading the demo will NOT work with licenses which are more than 6 months old. See Upgrade Accel ViewTIFF to purchase a upgrade license. New licenses are issued via e-mail immediately after purchase.
